good dude.i liked his accent. contrary to the other posts, he will be very helpful if you ask for it.

Mr. Ong is very helpful and nice.

Prof. Ong is very helpful; I got an A in his course. He explains math very well and if you go to his office hours, he will help you with whatever you need.

Professor Ong is really nice and really knows what he is doing, I hate his projects though. He sometimes doesn't explain things enough, but that is my only complaint.

i seem to be the only 140 kid here: he is a very smart man, teaches well and teaches fast. his math 140 is harder than most but that is not a bad thing. it will help later on. hes just past my caliber

hes good i liked him

He offers very many opportunities to improve your grade including extra credit and weekly homework assignments. If you tkae the time to do the work , there should be no problem recieving a good grade. Despite what people say, I love his accent.

Mr. Ong is a awesome teacher, I learnt a lot from him. For those who gave bad comments about him, you are just big losers and cheaters.......

Take this class if you think you are ready to be a college students. If you are juniors who want to be spoon-fed, not only you don't deserve this class, you don't deserve to be a college students.

His intro level math class is really easy if you know math. Other people tend to have trouble though. His homework assignments and online quizzes are very reasonable. He has a unique sense of humor that comes out now and then. He started the class by showing us his rating at this site!

Personally one of the best professor I've had on campus and the best math teacher I've ever had. He's very clear on what needs to be done and always offers help to students. His homework is reasonable and his tests aren't that hard.

Prof Ong is very helpful. I didn't interested in Math until I take his class.

Really smart, nice teacher. Tells random jokes a lot. If you have decent math skills, Amos is a good choice. He has an accent that takes awhile to get used to, so if you have weaker skills, you may want to take someone who would speak more clearly. Otherwise, great teacher.

Excellent teacher, did a good job explaining everything. Very fair tests, you actually have to know the material but if you expect less you don't need to be in Calc2 anyways.

Does a pretty good job at keeping the class interesting. Much better at teaching the subject than cupliari. Overall highly recommend Ong for this subject.

This is by far the best class in my schedule. Amos is a great teacher who makes the class interesting. From Calculus Trivia on fridays to getting fortune cookies for answering questions - this class is just a fun time.

He is the best professor I have had so far. The assignments and tests are fair. I like his method of teaching (take notes, practice problems in class while he walks around and helps you). I would recommend him for any math class.

Very Good.

sometimes difficult to understand but if you keep up with the homework and following along in the textbook it's not so bad

I was scared I wasn't going to be able to understand him but he doesn't have a difficult accent. Funny. Good Techer!

Good proff, willing to help his students out

Best calc 140 class available. Would recommend Amos to anyone wanting to get a good grasp on the subject and have fun doing it. Yes i did say fun. Not a big math person myself but found myself awake and ready to take on the mathematical world each and every class.

this dude is awesome.. you might not be able to understand all of what he says but its a good time just laughing at it.. but def take him if he's still left if you wanna learn and get some laughs out of it

amos is The Baron, a mathematician of such high caliber you wonder why he's even at behrend - amos is way out of our league but for some reason is willing to share a bit of his genius with us - rock on, amos - you are the best teacher i ever had!

Amos went over the questoins for the homework that we had to turn in that day. very easy. let us make sugestions for exams

The Michael Phelps of Calculus...

In google they really want you take Amos's class. Go ahead type in "Amos On" and see what the first result is, or even "Boon Wee". He is the king of calculus for a reason. Best math teacher I ever had.

Had him for Math 140 and Math 220. Ong is a funny guy and always willing to help his students!

Best Math Professor I've had. He's an extremely clear teacher. He makes complex ideas easy to understand. His homework policy is great: homework is due Friday and you go over it in class before handing it in. The class isn't overwhelming at all. Definately take him if you get the chance.

Best math professor I've ever had. He explains things very well and is very upfront on what will be on the exams. Do your homework and review regularly and you'll be fine. Ask questions in class if anything is unclear and get a tutor! I got an A and I am horrible at math.

Good teacher he may be hard to understand at first but he really makes the ideas clear I had him for both calc 1 and matracies and did well in both classes I definately would recommend taking class with him

Extremely helpful. Willing to take as much time as needed to review and answer questions. Recommend highly for an entry-level calculus class.

pretty easy class... fun guy..

Dr. Ong is one of the best professors I had in math, he is very clear, and he would give you your space to figure stuff out on your own then would help you if you got stuck, he occasionally would give bonus question, and he would always give sample exams from previous years before every exam.

Amos is a fantastic math professor. At first, I didn't like him because he had us memorize some derivatives and such, but after that, he turned out to be a very helpful teacher and a really funny guy. My friend and I actually wrote down a good number of the things he said in class just because they were so funny.

Amos is the best math professor I have had! He truly cares about his students understanding the material. He will willingly help you if you have any questions or do not understand something. The course can be difficult if you dont put in the necessary work. Be sure to do all the homework. Also do all the sample exams!!

Amos is a total boss, best math professor you could ask for. He is a crazy guy but hes hilarious, highly recommend Amos.

Fun class, fun guy, helpful, very nice teacher... Easy to learn, easy to score! :D take him!

Dr. Ong is the man. Amazing math professor and he makes you want to come to class everyday. He has a great sense of humor and will take the time to go over homework and any other questions. For Math 141 make sure you know your integrals/derivatives! Taking him for Math 251 next semester

I'll have to admit that I was a bit skeptical of Amos at the beginning of the semester. He did end up being an excellent calculus teacher. Gives a test and two quizzes per chapter and assigns a small amount of online homework. His partial credit is a bit harsh but if you do well and impress him he gives you bonus. He really enjoys teaching!

Also took him for MATH230. Great prof. Knows his stuff. Material isn't easy, gives great lectures and the tests follow them. Tests are difficult. Good bit of homework. Provided past exams for Calc II in '13. Did not for Calc III in '14. Gives a very difficult bonus question every two weeks. Won't be easy, will make you work, you will learn lots.

Dr. Amos is the man. This is calc 3, you will have to work in order to do well. His exams are definitely fair, if anything, they're closer to the easy side. He also gives an awesome review. Probably the most humble professor I've ever had, which is a breathe of fresh air. Dr. Amos will dance around the room if he thinks it will help him teach.

He is an amazing professor. His lectures are fun, although he usually goes pretty fast paced, so don't think you can skip class too much. You should expect homework and forget about it if you want an easy A. He can be a hard grader. He rally cares about his students and wants them to understand. If you're in for learning, I would really recommend.

Amazing Professor, lectures are always precise and on point to the syllabus. Explains really well when you visit his office hours. can even give you extra credit if you visit him too often. Will use anything that can help students understand a concept.

Amos is a great guy he really loves his Math. He says at the beginning of class do the book homework and the class wont be that hard so listen to him. The only way you can not pass the class is if you don't do the book homework which is optional.

DO THE HOMEWORK EASY A

His accent and comedy make the Calc 2 concepts we cover in class more dealable. He assigns A LOT of questions for the homework, but as long as you do the homework (about 2-3 hours per week), go to class, review even just a little (Calc 2 IS hard), and can grasp non-intuitive mathematics easily. You'll easily get an A. Amos is an AMAZING teacher.

Had to add the class late due to a registrar error, Amos taught me the material outside of normal office hours well enough to pass the first test in two days. Expects you to do the work and put in the time, but he'll match your effort 100%.

Took Calculus 2 with him over the summer. Very knowledgeable, truly cares about helping you, and will not purposely trick you on exams. He was available every day before/after class, and even offered to come in on Saturday to help if need be. Assigns a lot of homework, but gives practice exams from previous years to help you study. Recommend him.

Amos is the GOAT of all calculus professors. People claim calc 2 is the hardest calc, but Amos made the course easy. Explains material thoroughly, prepares you well for exams, and his lectures are enjoyable.

Amos is genuinely a good professor. As someone who struggled in Calc 1 I was able to excel in his Calc 2. He'll call on you in class and give weekly homework which obviously isn't preferable but it was for these two things that I was able to do incredibly well in Calc 2. If you put the work in you'll get the grade you deserve.

Absolutely wonderful professor. If it were possible, I would take all of my math courses with this professor. He is great at lecturing and explaining content, and he always comes to class with a positive attitude. I always look forward to this class!

I had him for calc 2 and he made it a breeze. He makes it hard in the beginning but thats only for the first 2 weeks then it gets easier. It is nice how he gives a practice exam before his exams that are similar or harder so if those are easy than itll be easy to get an A on the exam. He didnt post our grades in calc 3 but did in calc 2.

Amos is my favorite math professor at Behrend so far, he does a wonderful job explaining the material and his notes are well-organized. If you have a question on homework or any other material, you can email him and he'll respond pretty quickly to help with the solutions. He also provides multiple sample exams you can practice before a test.

I really don't understand why Professor Amos has such a low rating on here. He is probably the best math teacher I have had yet. He is an amazing person and a lecturer. He knows his material, and is caring about the students. I will definitely recommend him to anyone and would take him again if possible.

The weekly homework was thoroughly reviewed and provided great clarity on the topics. The lectures were always clear, and he provided many resources for practice. The book is helpful, but honestly unnecessary. He made this class much easier than I expected it to be, and I am now taking him again for Math 230.

He is a great Professor who will go through anything you need with a level of thoroughness that other math teachers does not focus on. He also tells you exactly what will be going on and what you will need to know and what you will be learning almost everyday making each class much easier than not knowing what you are learning.

Listen the most direct math teacher you will have. He does give you a lot of homework, but he does go over the homework in class and help you through it. If you like a teacher that's straight to the point Amos is your guy.

Amazing teacher, the best math professor I ever had. He always had clear explanation, I always knew what to expect on Exams, very fast grading, and he is always willing to help in or outside of the classroom.

Great Professor, took his class as a freshman and was worried about difficulty of college level math, but he does a good job of simplifying the content. Spends the first half of class explaining concepts with an example or two then gives worksheets and walks the room to give individualized help to each student.

Amos is quite easy to follow along with. He drives most of his lessons with examples from his notes so make sure you pay attention to the method of solving the problems. Notes can jump around every once in a while. He starts mostly every class off with a review of what you've talked about earlier in the week. Overall a very smooth course.

Amos is a very approachable professor. He is extremely kind and passionate about what he teaches. I was worried at first that I would not be able to understand him very well, as English is not his first language, but I was wrong. His notes are only examples on the board, but he gives us a lot of practice, either in the classroom or on homework.

I would totally would recommend this professor he might not be the best lecturer but he his a very fair grader. The review exams he did on canvas were amazing the exams are easy you only need to do the review and you will get an easy A.

A straightforward professor who breaks down concepts clearly. Lots of homework, but worth it - he explains everything thoroughly. unstuck ai was a lifesaver for study prep.

Amos is a great professor. There are pop quizzes, but he says that on the first day of class. They are worth 5 points only have one or two questions. He posts past exams on Canvas, and some of the questions are the exactly the same. He gives a lot of extra credit, he gave 30 extra points on the last homework of the semester. DON'T BUY THE TEXTBOOK

This man opened my eyes for math. I never had a professor teach as good as Amos does. Give him a couple weeks and you will realize why. He may be harsh with his critiques, but he cares about his students and will answer all questions. He gives out past exams and gives a lot of bonus for homework. He gets progressively funnier through the semester
